WATCH Dramatic New Footage: This Is What The U.S. Schooling ISIS Looks Like

Amid dimness and gunfire, a newly released video shows American and Kurdish soldiers freeing 70 hostages marked for death by ISIS during a dramatic raid In Iraq last Thursday. Army Master Sgt. Joshua L. Wheeler, 39, of Roland, Okla., was killed in the attack.

The video footage was taken from a helmet camera of a Kurdish soldier. With a glow coming through a barred window, soldiers can be seen moving in a darkened room with a huge ISIS flag behind them.

Men in robes with their hands on top of their heads come through a doorway and are searched before being moved along.

“Hold that guy there,” a voice with an American accent says at one point. “We got more coming.”

Footage of the raid near Hawija was released by the Kurdistan Regional Government and verified as authentic by a U.S. official.

CNN reported on Sunday that American Delta Force soldiers were in an “advise and assist role” on the mission, but were forced to become actively engaged after ISIS fighters were overwhelming the Kurdish troops who had entered the walled compound where the hostages were held.

Defense Secretary Ash Carter has called Wheeler a hero for his role in the rescue.

“As the compound was being stormed, the plan was not for the U.S….forces to enter the compound or be involved in the firefight,” Carter said Friday. “However, when a firefight ensued, this American did what I’m very proud that Americans do in that situation, and he ran to the sound of the guns and he stood up.”
